AI Weather Models Face Stability Issues Beyond Two Weeks, Study Finds

By PulseAugur Editorial · [2 sources] ·

A new research paper analyzes the long-term stability of AI weather models, identifying three failure regimes: blow-up, drift, and loss of seasonality. The study found that model stability is closely tied to how they handle small spatio-temporal scales, with stable models acting as denoisers and generating unique weather trajectories. These findings were validated through ablation studies on Vision Transformer (ViT) architectures. AI

IMPACT Identifies key factors for improving long-term stability in AI weather forecasting models.
